(Always good news from behind the Walls, eh?)
In essence, the blog mentioned above, the decree instead of giving a greater impetus to the Motu proprio explaining how to implement it to the bishops in the best way, would say that the old liturgy is just a concession to the "traditionalists" in recognition of their particular sensitivity. Still ... makers of this dilution would be Monsignor Charles Scicluna, promoter of justice in Malta under the Congregation for the Doctrine of the Faith, and Cardinal Antonio Canizares Llovera, prefect of the Congregation for Divine Worship
But, have no fear, apparently it's all untrue:
I have personally made the necessary checks and I can say that, according to sources inside the Vatican, the information given above "is entirely without foundation." The implementing decree is null and Canizares and Scicluna are not working in that direction.
The Pontifical Commission Ecclesia Dei, which is now chaired by the prefect of the Doctrine of the Faith, Cardinal William Joseph Levada, has already prepared the text of the decree, is waiting for the difficult work of translation to be finished, and expects to publish all (provided that the translations do not suffer delays) before Easter.
You'll forgive my scepticism if I say that I will wait and see...
